Reports interfaces in a class' <code>implements</code> list or an interface's <code>extends</code> list that
are already implemented by a superclass or extended by a superinterface.
Such declarations are unnecessary and may be safely removed.
<p><b>Example:</b></p>
<pre><code>
  class X implements One, Two {
  }
  interface One {}
  interface Two extends One {}
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  class X implements Two {
  }
  interface One {}
  interface Two extends One {}
</code></pre>
<!-- tooltip end -->
<p>
Use the options to not report on <code>Serializable</code> or <code>Externalizable</code>
  in an <code>extends</code> or <code>implements</code> list.
